Tank problems

[christyf5]

Thanks for the input Jason.

Its not like anything really grows super fast in my tank. If anything they are gaining mere millimeters of growth and those that are faster growers are just frags. I agree about changing up the placement of my powerheads just to see if that is the problem but those corals that are experiencing the tissue recession have ample flow IMO, I can see their polyps waving about, so I'm not sure about that. But heck, I don't seem to be sure about much in this hobby so it can't hurt.

I think I'm going to take your advice about the refugium. Its only been set up for a short while (since about November) but that doesn't mean it can't be causing problems all on its own. There isn't much in there and what is in there isn't doing all that fantastically well anyways (its mostly a cyano/gack factory) so I'll have a go at cleaning up the sand and restarting it.
